Avalanche Forecast

Reports have been very limited in this region. Observations of large avalanche activity from the recent warm up have been reported this week, including a cornice trigger on Thar Peak and wet debris reported from Cheam Peak (photos below).

Moving forward, avalanche activity is expected from wind loaded features in areas that have received fresh, dry snow.

Please consider sharing your observations on the MIN.

Up to 20 cm of settling snow sits over wet or crusty surfaces. On all but high north-facing alpine slopes, the upper snowpack is wet. Below 1800 m, it has melted substantially making approaches challenging.

Two persistent weak layers are buried within the upper 2 m of the snowpack. Avalanche activity is thought to be unlikely on these layers. However, large triggers like cornices may produce avalanche activity in shallow, rocky start zones.

Otherwise, the snowpack is generally well-settled and strong.

Tuesday Night

Cloudy, with flurries delivering localised amounts up to 10 cm. . 20 to 30 km/h west ridgetop winds. Freezing level 1000 m.

Wednesday

Cloudy, with flurries delivering localised amounts up to 10 cm. 10 km/h variable ridgetop winds. Treeline temperature -3 °C. Freezing level 1400 m.

Thursday

Clear skies. 30 to 40 km/h northeast ridgetop winds. Treeline temperature -2 °C. Freezing level 1600 m.

• Be alert to conditions that change with elevation, aspect, and exposure to wind.
• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
